Abstract:

Measurements of the paramagnetic g factors are made, using electron spin resonance at 8 mm wavelength, in solid solutions of gadolinium in yttrium, palladium and lutetium at temperatures between 60 K and 400 K. The measurements show that the g factor for the trivalent gadolinium ion in the metallic lattice varies significantly from the free ion value and is concentration dependent. For alloys containing more than 30 Gd in the Gd-Y alloy system, 80 Gd in the Gd-Lu alloy system, and for all concentrations in the Gd-Pd alloy system, the g factors are less than the free ion value. Lower concentrations of Gd in the Gd-Y and Gd-Lu alloy systems have g factors greater than the free ion value of 1.99. A qualitative attempt is made to explain this variation, using a model proposed by Kondo in which two interactions are considered. Author
